What JSON structure analysis is
A measurable view of document shape and complexity
Structure analysis counts containers and leaves, measures nesting depth, normalizes repeated array paths, and summarizes where objects and arrays occur without changing the source.
API inspection
Understand unfamiliar responses before integration
Profile saved API payloads to locate deeply nested resources, repeated collections, and the paths that carry most of the document structure before writing integration code.
Schema understanding
Explore shape before formal schema work
Use normalized paths and observed node types to understand a document before creating validation rules. This report measures existing data; it does not infer or generate a schema.
Data quality
Spot structural inconsistency with measured summaries
Compare child-count ranges and observed types at each path. Repeated array structures are grouped consistently, making unexpected shape differences easier to inspect.
Examples
Answer practical structure questions quickly
| Metric | Question answered |
|---|---|
| Maximum depth | How deeply nested is this payload? |
| Repeated paths | Which structures recur inside arrays? |
| Child range | Do objects at one path have different shapes? |

FAQ
Questions about JSON structure analysis
Does UtilityDock upload or store my JSON?
No. Your files never leave your computer. Validation, traversal, structural analysis, copying, and report creation all happen locally inside your browser.
How is maximum nesting depth measured?
The root is depth zero. Each property or array item below it adds one level, and the report returns the greatest measured depth.
What is a normalized JSON path?
A normalized path replaces individual array indexes with [*], grouping comparable values and repeated structures under one stable path.
What counts as a leaf value?
Strings, numbers, booleans, and null values are leaves. Objects and arrays are counted separately as containers.
Does the tool generate a schema or change my JSON?
No. Version 1 is read-only and does not generate schemas, edit trees, visualize graphs, optimize data, or call APIs.
